Abstract


With the development of the city construction, the fire happening chance isincreasing continuously. Currently, a fire probe installed in each building and the firealarm facilities have played an important role in discovering a fire and preventing afire in earlier period. But because of the product’s poor quality and equipmentsmanagement, the fire alarm system can not have an effective function. To the firealarm industry, how to make the computer data communication technique applied to afire probe in order to report to the police system in time, so that make use of thenetwork protocol and use of a social information resources well, exchange the systeminner part and the data information of the exterior in time, and to constitute a city ofdynamic state, the community of having a fire probe of the multilayer to report to thepolice rescue management the service network information system, is the topic thatneeds to be solve at present. The communication protocol don’t unify in current firefight network system and the building automation system don’t bring into with the firefight system is the problem that needs to be resolve urgently more.With these problems, the thesis issues the fire alarm and control. System basedon CAN Bus. The CAN Bus has many new design concepts, and these concepts arehelpful to advance the system’s real-time control, stability, flexibility, reliability, etc.The paper involves two parts. The first part mainly introduce the design ofintelligent node based on CAN Bus. By using AT90CAN32 single chip computer ascontrol node, the fire alarm system finally realizes the data acquisition to sensor. Thesecond part mainly introduce the design of the network based CAN Bus. By using thisnetwork, the system finish the PC supervises to control node.Besides, the thesis is also detailed to discuss the fire alarm and control system,CAN Bus intelligent node and PC control. By the SCADA software of Kingview, thePC also finishes the communications with fire alarm and control units. The paper involves the knowledge of single chip computer, network, communication, and PLC,etc. By using CAN Bus technology, the fire alarm and control system realize real-timecontrol, data acquisition and has better reference value.
